CARRIER.

Application filed January 26,

To all whom it may concern:

Be it known that l, Aannu'r H. NELLER, a citizen of the United States.residing at F airfield. in the county of Jefferson and State of Iowa,have invented a new and useful Improvement in Overhead Carriers, ofwhich the following is a specification.

Iv invention relates to that class of over lead carriers in which aplurality of trolleys are joined together by members connected theretoby swivels below the track, and it consists of an improvement in theconstruction of the parts whereby the wheels of the trolleys of onecarrier may be prevented from coming in contact with the wheels of thetrolleys of an adjacent carrier running on the same track, and also ofother improved features of the construction disclosed in thespecification and set forth in the claims.

ln the accompanying drawings forming part of this specification. Figure1 is a site view of a carrier embodying my invention. Fig. 2 is anenlarged transverse section on line 2-2 of Fig, 1. Fig. 3 is ahorizontal section on line 3-3 of Fig. 1. Fig. 4 is a side view of apair of carriers like that shown in Fig. 1 coainected together so as toform a carrier of'greater capacity. Fig. 5 is an enlarged transversesection on line 5-5 of Fig. 4. Fig. 6 is the same on line 6-6 of Fig. 4.Fig. 7 is a side view of a modified form of carrier. Fi 8 is ahorizontal section on line 8-8 of Fig. 7.

Referring to the drawings A represents a trackwa which will beoonnected'to an overheat support in any suitable manner known to theart, leaving a portion of the way free for the passageof the carrierwheels thereon. B represents a pair of trolley arms provided with wheelsW to run upon the track-way. As shown by the drawings, these trolleyarms are made in two pieces which are secured together so as to hold anaxle a for the wheels at their upperends, and their lower ends areformed with a recess for a swivel head. 0 repre .sents a pair of matingcastings which are bolted or riveted together and are each fitted withan n wardly projectin portion which form halt of a swivel hea D whichare mated together to form a complete swivel head to rotate in therecess in the lower ends of the trolley arms. a

These castings joined together form a Specification of Letters Patent.

connecting member for the trolleys, and are provided with recesses intheir lower central mating sides for the reception of the swivel head ofan attaching hook E. The connecting members (7 are provided with 60extensions F having laterally extended ends (1: which form bumpers oneach end to'contact with similar bumpers on adjacent carriers mounted onthe same track-way. B this means the wheels on adjacent trollc s will beprevented from colliding should t c carriers be run together on thetrackavay.

in the form shown in Fig. 4, there are two sets of trolleys andconnecting members C, which are 'oined together by means of a connectingbar ll. Two sets of castings I, each having a half swivel head on its llper cud. are secured to the o iposite sides 0 the ends of the bar H, amthe swivel heads formed by 'oining the two halves together are.ll'lsel'ttt in the recesses in the lower ventral meeting edges of theconnecting members C instead of the swivel head of the attaching hook Eshown in Fig. 1, thereby joining together the two sets of connectingmembers and the four trolleys.

A pair of mating castings J are secured to opposite sides of the lowercentral portion of the bar H. and are fitted with recesses in theirlower matin sides to re- 86 ceive the swivel head of the liook E, whichin this case is transferred from its position shown in Fig. l to thatshown in Fig. 4.

F ig. 7 shows a modified form of carrier consistin of a pair of trolleysB with 90 wheels 6, joined b v means of swivels to the ends of aconnecting bar K, The ends of the bar K are extended beyond the outer;edges of the wheels W and are rovided with laterally extended bumpers 1which are composed of pieces of sheet metal somewhat carved in theircentral portions crossing the ends of the bar K, and the lateralextensions are doubled back and are secured to the sides of the bars bybolts, screws or mm s.

These carriers have frequently to run around curved track-ways in whichcases only the inner laterally extended edges of the bumpers can come incontact with each other. 0

may be extended to form carriers with more wheels and greater capacityby adding lar er and long connecting bars.

he castings (I bein v in two mating pieces can be l'flltdll' placed onthe swivel head of the book It, and being used with trolley arms made oftwo pieces, the swivel heads formed by the halves on the castings C canbe readily inserted in the swivel recesses of the trolley arms. lhe samemay be said of the half swivel head on the castings I, which, whenplaced together, form a com- 1 lete swivel head which is easily insertedin he swivel recesses of the castings before they are joined together.The swivel head of the hook E may also be easily inserted in the swivelrecesses of the castings J in the same manner, thus forming a structureeasy to assemble and capable of being expanded.

In the forms shown in Figs. 1 and l the load to be carried is attachedto the hooks E but in the form shown in Fig. 7 the load may be connectedto the carrier by means o l' attachments secured to the bar K or in anyother suitable manner.

Vi'hat I claim is s 1. 1n overhead carriers :1 pair of trolleys adaptedto run on an overhead. track-way and having trolley arms constructed oftwo pieces joined together with a semi-circular recess in the matingsides of each of their lower ends, and a pair of castings forming aconnecting member for the trolleysflearh casting having half of a swivelhead on the upper edges of its opposite ends, and a seniicircular recessin its lower mating central portion adapted to receive and, when joinedtogether, to hold a swivel head, said halt swivel heads when joinedtogether to form a complete swivel head adapted to swivel in therecesses of the trolley arms and to connect the trolleys together.

2. In overhead carriers, two pairs of trolleys joined together byconnecting mom-- gbers each member having a seinvcircular "recess in itslower mating central portion, a bar to join said connecting memberstoether, and two pairs of castings, each having a half swivel head vonits upper end, said castings being secured to the opposite sides of eachof the ends of the connecting bar, and the half swivel heads whenjoined' together to form a complete swivel head adapted to swivel in therecesses in the con neeting members and to join them together.

3. In overhead carriers, two pairs of trolleys joined together byconnecting members, each member having a semi-circular recess in itslower mating central ortion, a bar to join said connecting mem erstoether, two pairs of castings, each having a half swivel head on itsupper end, said castings being secured to the opposite sides of each ofthe ends of the connectin bar, and the half swivel heads when joinfil toethr to form a complete swivel head a apted to swivel in the recesses inthe connecting members and to join them together, and a pair of castingssecured to opposite sides of the lower central portion of the connectingbar, each casting having a semi-circular recess in its lower mating sideadapted to receive and hold a swivel head.

4. In overhead carriers, :1 pair of trolleys adapted to run on anoverhead track-way, a connecting men'iber swiveled to the lower ends ofthe lrollevs below the track-way, the ends of said connecting memberbeing extended to a line vertically beyond the outer edges of thetrolley wheels and laterally extended to form broadened bumpers tocontact with the frame of an adjacent ear rier.

5. In overhead carriers, a pair of trolleys adapted to run on anoverhead track-way, a connertinp member swiveled to the lower ends ofthe trolleys below the tracleway, the ends of said connecting memberbeing extended. to a line vertically beyond the outer edges of thetrolley wheels, laterally extended and curved on their outer faces toform bumpers to contact with the frame of an adjacent carrier.

13 in overhead carriers a pair of trolleys adapted to run on an overheadtracleway, a connecting member swiveled to the lower ends of thetrolleys below the track-way, the ends ot said connecting member beingextended to a line vertically beyond the outercdges of the trolleywheels and strips of metal having their outer faces laterally extendedand curved applied to the ends 0 the bar to form bumpers, and the endsof the strips being doubled back and secured to the sides of the bar.
